Specification of Letters Patent.

1 Ap lication filed May 20, 1911. Serial No. 628,359.

Be it known that I, ALFRED M. citizen of the United States, residing atFranklin, in the, county of Venango and State of Pennsylvania, haveinvented certain new and useful Improvements in Stereopticons,'- ofwhich the following is a specification.

' The .ob'ect, construction, and operation of my improved stereopticonare herein set forth with sufiicient clearness-to enable those skilledintheart to which it appertains to make and use the'saine, reference beinghad to the accompanying drawings which form a part of this application,the several views whereof are as follows:

Figure 1 is a' front elevation of ofmy stereopticon showing the sameinclosed for out-door use. 'Figs. 3, a, 5,6 and 7 are details.

The same reference numerals are applied to identical parts in all theviews. 7

The object of my invention is, to providea stereopticon for theparticular purpose of displaying advertising matter, though otherinformation or illustrative matter may be displayed thereby as desired.I

The construction of my improved stereopticon is as follows: I constructa wheel composedof a hub 1, having a number of'radial arms 2, each-ofwhich is provided upon its outer end with a plate or transparencyholder3. Said wheel is mounted between brackets 4 and 5 so as to revolvevertically. Mounted-upon one side of said wheel and adjustablypositioned with reference t ereto, is a condenser 6, and positioned inproximity to said condenser is a suitable'light 7.

Upon the opposite side of the wheel, and in correct register oralinementwith the plate V number of pins 9-which project outwardly from said hubin a line parallel with the axis of said wheel. Below the center of saidwheel is revolublv mounted a shaft 10, suit-'.

SMILEY,-

my im proved stereopticon, Fig. is'a side elevation able bearings forwhich are provided in brackets 5 and 11. The end of shaft- 10approximate to the wheel projects through its bearing and has an arm '12rigidly affixed thereto which, as the. shaft 10 revolves, is

adapted to engage a pin 9 and revolve wheel 1 sufliciently to bring asuccceding approximate. frame 3 into'its proper position of registrywith the lens and light, sothat its subject will be thereby projectedupon the screen. I arrange to .revolve shaft 10 con.- tinuously, and themechanism provided for this purpose is-as follows: T 0 said shaft-10 issecured a worm-wheel 13- which meshes ith d i d i en vbyzaworni 14 whichis suitably mounted in bearings carried by the bracket 11. Upon theworm-shaft is aflixed a pulley 15 which. receives power flUIH-HIIelectric motor 16. this arrangement, it-

'will beradily understood that while'shaft '10 revolves constantly,wheel 1 is moved intermittently, each movement being an amountsiifiicient to bring'one of the various .holders into register with theprojecting medium where the sameyis caused to rest for a certaininterval 'of'time, said interval being during one revolution of shaft10.

In order to insure a positive stopping'of' the wheel in the desiredposition, 'and its retention there during the allotted interval, Iprovide'a resilient detcnt, which is shown in section in F ig. 4, theconstruction of which is as-follows: In the face of the wheeLhub areformed a number of depressions 18. In the-bracket 5 is inserted atubular post '17, which is arranged-withits outer open end in closeproximity to the face of the wheel-hub. -Within the bore of said post isplaced a ball 18, arranged to occupy a depression 18, when said depression passes or is positioned in front of post 17. Ball 18 is pressedoutwardly by means of a spiral spring 19, the pressure of which.

the following construction: The bracket 21- which carries the lens ismounted upon two rods 22, 22, (Fig. 7,) so that it may slidelongitudinally thereon,a' screw-threaded rod 23 passes through thebracket 21, and the slceve24: is formed into a nut to engage said 5 rod23, and by turning said rod by means of the wheel'25, the desiredadjustment may be obtained. I also provide for adjusting the condenser 6with reference to the light 7,

. Which'is accomplished in the followinginan' l0 ner: The -bracket -26,that-carries the said condenser,'is mounted to slide upon the Ways 27(Fi-g. 6) and by turning the screw28, WhlCl'L passes through thescrew-threaded yoke 29, I said bracket and-'thethereto at-- -tachedcondenser may be adjusted as desired; A thunih vvheel 80 is attached toscrew 29 for the purpose of revolving said screw. v

In Fig. 2 I have shown my improved 20 stere'opti'con inclosed in a boxor cas'e,-as it is constructed for outdoor service-for advertisingpurposes, and this View shows an electric switch 31, wit lrconductors32, passi ing to the light and other conductors 33 passing to. themotor; 16.

mission between the motor and pulley '15 may be substituted for a belt,as for instance a chain or gears. j I am. aware of the constructionshown in certain Letters Patent of the United States issued to WilliamG. Spiegel 'on the 12th day of April, 1892 for magic lantern advertisingapparatus, but I hereby expressly forth.

Any suit-able light may be used, also any suitable trans-i What. I claimand desire to secure by Letters Patent is w In astereopticon of theclass specified, the combination ofa continuously illuminated projectingdevice consisting of a 'contirnia ously illuminated lamp, a horizontallyand vertically adjustable condenser, and a lens adjustable in thedirection of said condenser, With' movable transparency holders arrangedto contain transparencies and to pcprojecting device, saidtransparency-holder consisting of a'wheel composed of a hubnnd aplurality of radial 'arms'attached to said sition the same in projectiveregister in said hub, each carrying a transparency-holder at v its outerend, a shaft in said hub for revolubly inounting's'aid ,Wheel, pins,corresponding in number to the number of said arms andholders,projecting horizontally from said hub, a revolubleshaft arrangedwith its axis in aline nentfwith the axis of said firstdisclaim suchcombination as is therein set G.
